About 20 full-time jobs will be added downtown on March 10 when a company which assists hospitals and physician offices with bill collections moves into the former Corporate Research International building at 129 E. Crawford St.

IntelliHARTx, which stands for “intelligent treatment for healthcare account resolutions,” plans to grow to 200 to 250 employees in five years, said Chief Executive Officer John Kunysz. At least the first 50 employees will be paid about $33,000 per year, the State Development Services Agency reported.

The state today awarded IntelliHARTx a payroll tax credit on the first 50 jobs. The workers will be mainly health care account resolution representatives, Kunysz said.
